# HitPawVideoEnhance - ComfyUI Built-in Node Documentation

> Complete documentation for the HitPawVideoEnhance node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The HitPaw Video Enhance node uses an external API to improve the quality of videos. It upscales low-resolution videos to a higher resolution, removes visual artifacts, and reduces noise. The processing cost is calculated per second of the input video.

## Inputs

| Parameter          | Description                                                                                                                                                      | Data Type     | Required | Range                                                                                                                                                                                                                                        |
| ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`            | The AI model to use for video enhancement. Selecting a model reveals a nested `resolution` parameter. The available models and their supported resolutions vary. | DYNAMIC COMBO | Yes      | `"Portrait Restore Model (1x)"`<br />`"Portrait Restore Model (2x)"`<br />`"General Restore Model (1x)"`<br />`"General Restore Model (2x)"`<br />`"General Restore Model (4x)"`<br />`"Ultra HD Model (2x)"`<br />`"Generative Model (1x)"` |
| `model.resolution` | The target resolution for the enhanced video. The `"8K"` option is only available for models other than `"Generative Model (1x)"`.                               | COMBO         | Yes      | For `"Generative Model (1x)"`: `"original"`<br />`"720p"`<br />`"1080p"`<br />`"2K/QHD"`<br />`"4K/UHD"`<br /><br />For all other models: `"original"`<br />`"720p"`<br />`"1080p"`<br />`"2K/QHD"`<br />`"4K/UHD"`<br />`"8K"`              |
| `video`            | The input video file to be enhanced.                                                                                                                             | VIDEO         | Yes      | N/A                                                                                                                                                                                                                                          |

**Constraints:**

* The input `video` must be between 0.5 seconds and 60 minutes (3600 seconds) in duration.
* The selected `resolution` must be larger than the input video's dimensions. If the video is square, the selected resolution must be larger than its width/height. For non-square videos, the selected resolution must be larger than the video's shorter dimension. If the target resolution is smaller, an error will be raised. Choose `"original"` to keep the input video's resolution.

## Outputs

| Output Name | Description              | Data Type |
| ----------- | ------------------------ | --------- |
| `video`     | The enhanced video file. | VIDEO     |
